2 Claims. (C1. 98-46)- This invention relates to portable chimneys and more particularly to a knocked-down type chimney which may be shipped in disassembled relation and set up for use at the site of the building upon which it is to be used.

The principal objects of the present invention are to provide a chimney for building structures which may be shipped in knocked-down form to facilitate packaging for shipment and which may be quickly and easily assembled for erection on the building at the site thereof; to provide means for preventing moisture from entering the opening in the roof of the building structure; to provide an insulation for the top and sides of the wall of the structure to impede condensation; to provide a base having upwardly extending walls for the reception of the chimney portion of the structure, some of the upwardly extending walls being turned inwardly to deflect the moisture or condensation which may get into the interior of the chimney; to provide a ventilator for the chimney whereby the air will not be directly contacting the opening in the top of the chimney; to provide means on the respective corners of the knocked-down structure for interengaging the corners one with the other for quick assembly and disassembly; to provide means for fastening the various parts in assembled relation, and to provide a structure of this character simple and economical to manufacture.

In accomplishing these and other objects I have provided improved details of structure the preferred forms of which are shown in the accompanying drawings, wherein:

Fig. 1 is a perspective view of my knocked-down chimney in assembled condition.

Fig. 2 is an enlarged vertical cross-sectional view through the chimney.

Fig. 3 is a perspective view of the parts shown in disassembled relations.

Referring more in detail to the drawings:

1 designates a chimney embodying the features of my invention comprising, a base 2 having a center opening 3 with upstanding walls 4, 5, 6 and 7 surrounding said opening, the upper edges of the walls 4 and 6 being sloped inwardly as indicated at 8 and 9 for a purpose later described. The end edges of the walls 4 and 6 have tongues as indicated at 10 and are extended over the walls 5 and 7 and are welded orotherwise suitably secured thereto.

The chimney portion 11 is provided with side walls 12 and 13 and end walls 14 and 15 made in separate pieces and when formed together are adapted to fit over the upstanding boss portion of the base 2 formed by the upstanding walls 4, 5, 6 and 7. The walls 12, 13, 14 and 15 are adapted to be fitted together so that they may be shipped in disassembled relation to conserve space for packing in shipment. The end walls 14 and 15 are provided at their respective edges with slightly inturned portions 16 forming an oifset portion 17, which is turned upon itself providing a hook portion 18 with a groove 18'. Each edge of the sides 12 and 13 are provided with a laterally turned edge 19 and then turned parallel with the laterally turned portion forming a hook 20 and a groove 21 so that the sides 12 and 13 may be fitted with the end portions by sliding the sides from the top thereof so that the hooks 18 and 20 will engage in said groove to hold the walls securely together. When the chimney portion 11 is assembled, it is fitted over the boss portion of the base and the laterally turned bottom edges 22 of the end walls and bottom edges 23 of the side walls, fit on the base 2 adjacent the upstanding boss portion. The sides 4 and 6 of the upstanding boss portion are provided with openings, as indicated at 24 and the side walls 12 and 13 are provided with aligning openings 25' for receiving screws or the like, as shown at 26 (Fig. i), for holding the chimney portion on the base. The upper edges of the sides 12, 13, 14 and 15 are turned laterally forming flanges as indicated at 27 (Fig. 3).

A cover frame 28 is provided for engaging over the top edge of the chimney portion 11 and rests on the upper edges 27 of the sides and end members 12, 13, 14 and 15. The cover frame comprises side walls 29 and 3t} and end walls 31 and 32 fastened together by screws or the like 33 and 34. The side and end walls are substantially U- shaped in cross-section as shown in Fig. 2 and the lower side thereof has an upturned flange 35 which engages against the side and end walls 12, 13, 14 and 15 and the upper edge has an upwardly extending flange 36 and then turned inwardly as indicated at 37 which engages over the inturned edge 27 of the side and end walls of the chimney portion. The cover frame is provided with a central ope-ning 38, and is partly covered by a cover 39 having a substantially plane surface 40. The cover 39 is provided with depending flanges 41 which are adapted to engage over the upwardly extending flanges 36 of the cover frame 27, whereas the outer portion of the surface 49 engages over the inwardly turned portion 37. Two opposite sides of the flanges 41 are provided with an opening 42 for receiving a screw 43 adapted to engage aligned openings 44 in two sides of the upstanding flange 36 on the cover frame 28. The ends 14 and 15 of the chimney portion 11 are provided near their upper edges with openings 45 which align with the openings 42 and 44 so that the screws 43 extending therethrough will retain the cover 39, frame 28 and chimney portion 11 in assembled condition.

The cover 39 is provided with a central opening 46 to which is fitted a short ventilating pipe 47. A ventilator 48 is provided for the cover 39 and surrounds the ventilator pipe 47 and extends upwardly from the cover. It is of any desired shape and the walls are provided with feet or the like 49 secured to the plane surface 40 of the cover 39 by screws 50 and the ventilator has an open top 51. The wall 52 of the ventilator 48 is of one piece construction and is provided with cutaway portions 53 at the four corners thereof to allow air to enter and water to escape between the ventilator and the cover 39. The vent pipe 47 extends slightly above the cover 39 and cutaway portions 53 as best illustrated in Fig. 4. An air deflector 54 is secured in the open top 51 of the 55 of smaller diameter than the ventilator 48 and is secured to a cross-member 56 having its ends 57 secured to'thei upper edge of the ventilator by screws. or the like.

as indicated at 58 so that the air will. notdirectly, contact the ventilator-pipe 47 but willbe defiectedaround the deflector-plate 54to around'the edge-of the pipeas illustrated in Fig. 2.

It'will be obvious the chimney embodying thevfeatures of'my invention may be made of any suitable. ma-- terialfsuch'as metal, plastic, or the like, which simulates a chimney, and may also be painted'in colors to indicate brick or stone. The chimney may be utilized for utility purposes or it-may be merely for ornamental purposes; When used for ornamental purposes it may be seton top: of the roof-59 of a house which is shown to be a sloping roof and the side 14 of the chimney portion be shown slightly shorter than the opposite side 15 to accommodate the sloping of the roof.

Itwill be obvious that the base of the chimney maybe'made to fit the ridge combof a roof and, in which event, the side members would be of the same length and the end members would be notched (not shown) to take care of the ridge of a roof.

The chimney may be utilized for decorative purposes wherein there is no opening in the roof of the structure upon which it is used, or it may also be used for actual taking away of smoke by the usual chimney to the-roof and then a pipe (not shown) connecting with the vent pipe 47 to the chimney.

When the chimney is shipped in knocked-down condition the base 2 is then set up and fastened to the roof 59-by nails, screws or the like as indicated at 60' (Fig.- 2) so that the chimney may be assembled on the roof but it is preferable to assemble the separate parts and then apply it'to the roof after it is assembled; As heretofore stated, it can be placed on top of the shingles or it-may be applied to the sheeting 61 as illustrated at Fig. 2, and the shingle placed over the base 2 as is the usual practice.

In assembling the sides and ends of the chimney portion'together, one of the sides and ends are joinedtogether by sliding of the sides down over the looped or hooked portions 18 and 20 of'the structure (Fig. 6) until they are even at the top. The other side is: then inserted by pushing the same from the top' so that the hook portions engage together to form the chimney portion ofthe device. The cover frame 28 is then inserted over the top of the chimney portion 11 and cover. 39 is then placed on the upstanding flange 36 and the screws 43 inserted through the openings 42, 44 and 45 to hold the device in assembled relation. The chimney portion 11' is held onto the base by the screws 26 (Fig. 1).

In Fig. 7 I have shown a modified form of interconnecting side and end members the end 15 being turned laterally to form a flange 62- andthe side 13 is provided with a hook member made by folding the corner edge backupon itself asv indicated at 63 and then outwardly from the end and parallel therewithforming a groove 64to which the flange62 engages. The extreme outer end edge 65 is then turned laterally along side the end 15 to retain the members together.

In Fig. 8 I have illustrated a further modified form of the invention wherein the side member 13 is turned inwardly and folded along side itself as indicated at 66 and then laterally and parallel with the portion 66 as indicated at 67 forming a groove 68 in which the laterally turned end 6% of the end 15 is adapted to engage. Aligned openings as indicated at 7i) are provided for receiving screws, bolts, or the like 71 to retain the respective corners in engaged relation.

in Fig. 9 Ihave provided a still further form of connecting the corner members together wherein the respectivezedges of'the side 13 and the end'lSi are turned laterallyupon themselves as'indicated at 72 and'73 forming grooves v'M'and 75; In'assemoling thisformof'structure the corner edges of the sides and ends are placed together and a connecting strip 76 substantially L-shaped having flanges 77 and 78 isprovided to engage in the grooves 74 and 75.

In order to aid in the control of condensation on the inside walls of the chimney portion due to difference in temperature from the heat from the building structure and particularly the stove pipe or chimney (not shown) I provided a layerof insulating material 79 on the side and end walls of the chimney portion 11 and a layer 80 of the insulating material underneath the cover 39 as best illustrated in Fig. 2. The insulating material may be of any character such as rock wool, sheet rock, fiber glass or the like and is applied to the walls by adhesive or other suitable material. The lower end of the sheet material extends below the upstanding walls 4, 5, 6 and 7 of the base 2 as indicated at 81 (Figs. 2 and 5) so that any moisture absorbed by the. insulating material will drain around the boss formed bythe walls and be drained off on the roof structure. If no insulation material is used the inturned flanges Sand 9 ofthe walls 4 and 6,

as well as the slightly inwardly inclined walls-5 and 7, will also deflect any moisture collecting on-the side and end walls so that it will drain away instead of; entering the opening in the base 2.

It will be obvious from the foregoing that .I' have provided an improved portable chimney which maybemanufactured and packed for shipment in disassembledrelation and be quickly and easily assembled for use on the building structure on the site thereof.
